These cysts are made of dinosporin, a resistant, complex organic compound that enables the cysts to be preserved as microscopic fossils in sediments hundreds of millions of years old.Technique: Autofluorescence of the sample was recorded by confocal microscopySample courtesy of Dr. John Firth, Ocean Drilling Program at Texas A&M UniversityTags:Fossil // Fluorescence
